TECHNICAL FIELD

The present invention relates to a polyamine derivative and a polyol derivative having a novel piperidylaminotriazine skeleton and a preparation process thereof. Further, the present invention relates to a stabilizer for an organic material comprising the compound, a stabilization method for the organic material by the compound and the organic material stabilized by the method.

BACKGROUND ART

Organic materials, particularly polymer materials including polypropylene are light weight and high in shape freedom and are widely used for applications in which weather resistance is required in the range from automobile-related usage to building material-related usage, agricultural film usage and household electric article-related usage. A substance which imparts weather resistance to these polymer materials is a light stabilizer and among them, a hindered amine based light stabilizer (HALS: Hindered Amine Light Stabilizer) is usually used as an indispensable resin additive at present.

The existing HALS is classified broadly into a low molecular weight type compound having a molecular weight of 1000 or less and a high molecular weigh type compound having a molecular weight of 1500 or more and by separate usage or usage in combination of these compounds, in the usage of both thin articles (the thin layer-like polymer material) and thick articles (the polymer material other than the thin article), stabilization relative to light is intended. However, in the low molecular type compounds, it is difficult to continuously impart a stabilization effect in the thin article usage. Further, there is a problem of bleeding out, fogging, sick house or the like originated in the low molecular weight type compounds. Whereas, in the high molecular weight type compounds, the stabilization effect is small in the thick article usage and it is further known that pigment dispersibility is also insufficient. Further, even in combination usage of compounds of both types, an additive/synergistic effect is not generally recognized. Further, in both low molecular weight type compounds and high molecular weight compounds, it is recognized to contaminate a metal die at molding and there is a problem in that increase in the number of cleaning of the metal causes reduction in productivity.

In the polyamine derivative having the piperidylaminotriazine skeleton, as the compound in which all amino groups derived from the polyamine main skeleton linked to the triazine ring are linked to only one methylene group in the polyamine main skeleton respectively of the compound having 3 or more triazine rings, there are compounds described in Patent Document 1 and compounds disclosed in very wide Marcush structure of Patent Documents 2 to 8. Further, in the polyol derivative having the piperidylaminotriazine skeleton, as the compound in which the polyol main skeleton is a hydrocarbon group of the compound having 3 or more triazine rings, there are compounds disclosed in very wide Marcush structure of Patent Documents 2 and 7. However, these compounds involve problems described above or problems of difficulty in obtaining the raw material for production and problems of production process such as extended production step (including a production step of polyamine and polyol, i.e., intermediates).

[Method for Stabilizing Organic Material]

A method for stabilizing the organic material with respect to deterioration by light, heat, oxygen, ozone and an electromagnetic wave such as X ray and γ ray is to mix at least one kind of compound represented by the general formula (1) or its salt or a mixture thereof in the organic material. The compound of the general formula (1) or its salt or the mixture thereof can be used at various ratios depending on the property of the material to be stabilized, the final use and existence of other additives.

In general, the compound of the general formula (1) or its salt or the mixture thereof is used appropriately in an amount ranging from 0.001 to 15 parts by weight, preferably from 0.01 to 5 parts by weight, and more preferably from 0.05 to 3 parts by weight, for example, relative to 100 parts by weight of the organic material to be stabilized.

The compound of the general formula (1) or its salt or the mixture thereof can be added to the organic material in various convenient steps before preparation of a forming material, for example, before, during or after polymerization or cross-linking. Further, they can be mixed in the organic material in the pure form or in the form of filling in wax, oil or polymer.

The compound of the general formula (1) or its salt or the mixture thereof can be mixed into the organic material by various methods, for example, dry mixing in the powder form or wet mixing in the form of solution or suspension or in the form of master batch. In the operation, the organic material can be used in the form of powder, granule, solution or suspension or in the form of latex.

The material stabilized by the compound of the general formula (1) or its salt or the mixture thereof can be used, for example, for manufacturing a molded article, a film, a tape, a monofilament, a fiber, a surface coating, a coating composition or the like.

[Additives which can be Used in Combination]

The organic material containing the compound of the general formula (1) or its salt or the mixture thereof can be added, if desired, in combination with other usually used additives for the organic material, for example, an anti-oxidant, a UV ray absorber, a photostabilizer, a pigment, a filler, a plasticizer, an anti-static agent, a flame retardant, a lubricant, a corrosion inhibitor and a metal inactivating agent.
